A way to manage the context menu entries would be to edit them right in the Windows Registry. A more secure solution is by the use of software like Shell Menu View by NirSoft. The portable software displays a list of all registered shell extensions of a Windows operating system with information like the menu name, the file extensions or the path of the application.

The tables can be sorted in various ways and there is a search to find that one extension that you want to edit right now. A right-click on any row in the software program opens a context menu that provides options to disable or enable an extension, open the Registry key of that extension or print a list of all or selected items.

ShellExView is a portable application that runs on most Windows operating systems but works best in Windows XP and Windows 2000 because they can make use of the disable feature.
